In this work, we define a novel Internet service, called ABE (Alternative Best-Effort), which allows interactive multimedia applications to receive low queuing delay within the existing best-effort Internet. We then develop and analyse a number of innovati ...
We use active and passive traffic measurements to identify the issues involved in the deployment of a voice service over a tier-1 IP backbone network. Our findings indicate that no specific handling of voice packets (i.e. QoS differentiation) is needed in ...
We present a model of TCP flows suited to Internet backbone traffic, where links are usually not congested. We characterize the traffic using information on flows, i.e., arrival time, size, and duration. The major contribution of this paper is a model capt ...

We consider a FIFO multiplexer fed by flows that are individually constrained by arrival curves, and look for the best possible arrival curve for every output flow. This problem arises in scenarios where aggregate multiplexing is performed, such as differe ...

We propose Alternative Best-Effort (ABE), a novel service for IP networks, which relies on the idea of providing low-delay at the expense of maybe less throughput. The objective is to retain the simplicity of the original Internet single class, best effort ...
Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...
The min-plus theory of greedy shapers has been developed after Cruz`s results on the calculus of network delays. An example of greedy shaper is the buffered leaky bucket controller. The theory of greedy shapers establishes a number of properties such as th ...
